Declared quarterly dividend of C $0.60 per share for shareholders of record on June 1, 2018

TORONTO, ON (May 3, 2018) – Norbord Inc. (TSX and NYSE: OSB) today reported Adjusted EBITDA of $170 million for the first quarter of 2018 versus $103 million in the first quarter of 2017 and $204 million in the fourth quarter of 2017. The year-over-year improvement is primarily due to higher North American oriented strand board (OSB) prices and shipment volumes, as well as higher European panel prices. The quarter-over-quarter decrease is due to lower North American OSB price realizations and shipment volumes. North American operations generated Adjusted EBITDA of $156 million compared to $102 million in the same quarter last year and $195 million in the prior quarter. European operations delivered Adjusted EBITDA of $18 million versus $6 million in same quarter last year and $12 million in the prior quarter.

“Our first quarter Adjusted EBITDA result is 65% higher than this time last year and reflects the continued improvement in new home construction activity and other OSB end uses,” said Peter Wijnbergen, Norbord’s President and CEO. “Our mills ran slower in what was a particularly harsh winter, impacting costs; however, the additional production from our recently restarted Huguley, Alabama mill helped mitigate this headwind. At the same time, North American benchmark OSB prices have been unseasonably strong due to steady demand, continued low apparent inventory levels and supply constraints stemming from weather-related logistics challenges, particularly in the west.”

“Our European business delivered $18 million of Adjusted EBITDA, its best result in over a decade. Our key markets remain strong as robust demand growth across the UK and Germany supported improved prices. I’m pleased with the progress our Inverness, Scotland mill is making as the new continuous press line ramps up and we anticipate the new finishing end installation to be complete by the end of this year.”

“As we enter the spring homebuilding season, North Central benchmark OSB prices are currently 22% higher than this time last year. Given our extended order files and customer reports of lean inventories, we don’t believe that the publicly-announced capacity additions will fully meet the forecasted OSB demand growth in the near term. In Europe, our panel business is on track for an excellent year as OSB continues to gain market share versus plywood.”

Norbord recorded Adjusted earnings of $96 million or $1.10 per diluted share ($1.11 per basic share) in the first quarter of 2018 versus $50 million or $0.58 per share (basic and diluted) in the first quarter of 2017 and $123 million or $1.41 per diluted share ($1.42 per basic share) in the fourth quarter of 2017. Adjusted earnings exclude non-recurring or other items and use a normalized income tax rate:

Market Conditions

In North America, year-to-date US housing starts were up 8% versus the same period in 2017, with single-family starts, which use approximately three times more OSB than multifamily, increasing by 7%. The seasonally adjusted annualized rate was 1.32 million in March, which is 11% higher than the pace at this time last year, while the pace of housing permits (the more forward-looking indicator) was 1.35 million. The consensus forecast from US housing economists is for approximately 1.29 million starts in 2018, which suggests an 8% year-over-year improvement.

North American benchmark OSB prices increased significantly during the first quarter of 2018 as end-use demand remained robust while severe winter weather hampered both production and logistics. Average benchmark prices were significantly higher than the same quarter last year, but more or less in line with the prior quarter when prices pulled back following the severe hurricane season that temporarily pushed up demand and prices. Of particular note, the Western Canadian benchmark price increased 41% through the first quarter of 2018 and finished the quarter on par with the North Central benchmark, demonstrating the tightness in that region as the spring building season commences. The table below summarizes average benchmark prices ($ per Msf, 7/16-inch basis) by region for the relevant quarters:

In Europe, Norbord’s core panel markets continued to strengthen, with robust OSB demand growth in both the UK and Germany. In local currency terms, average panel prices were up 25% versus the same quarter last year and up 10% from the prior quarter.

Performance

North American OSB shipments increased 6% year-over-year due to additional production from the Huguley mill that restarted during the fourth quarter of 2017, but were 3% lower quarter-over-quarter due to fewer fiscal days. Norbord’s specialty sales volume (including industrial applications and export markets) increased by 22% year-over-year and represented approximately 25% of the Company’s North American OSB sales volume.

Excluding the curtailed Chambord, Quebec mill, Norbord’s operating North American OSB mills produced at 94% of stated capacity, unchanged from both comparative periods as the additional production and capacity from the restarted Huguley mill was offset by seasonally slower line speeds in the current quarter.

Norbord’s North American OSB cash production costs per unit (before mill profit share) increased 2% versus the same quarter last year due to higher resin prices and the stronger Canadian dollar, partially offset by the timing of annual maintenance shuts and related costs. Unit costs increased 5% compared to the prior quarter due to fewer fiscal days in the quarter, seasonally slower line speeds and higher resin prices.

In Europe, Norbord’s shipments were 4% lower than the same quarter last year due to timing of shipments but were 5% higher than the prior quarter due to seasonality. The European mills produced at 86% of stated capacity in the quarter compared to 98% in the same quarter last year and 94% in the prior quarter. Capacity utilization decreased versus both comparative periods due to the restated annual production capacity to reflect the new OSB continuous press line in Inverness that was substantially completed in the fourth quarter of 2017. Production from the expanded Inverness mill will not significantly increase in 2018 as the mill shifts from the old lines to the new. Norbord expects to see increased production volume from Inverness starting in 2019 once the new finishing line installation and commissioning are complete.

Severe winter weather conditions in both North America and Europe caused more seasonal operating challenges than usual at the mills, hampering the Company’s ability to realize Margin Improvement Program (MIP) gains to-date this year. The Company generated $3 million of MIP gains in the first quarter of 2018 due to the timing of planned annual maintenance shuts and related costs, partially offset by costs associated with executing on strategic initiatives. MIP is measured relative to the prior year at constant prices and exchange rates.

Capital investments were $50 million (including intangible assets) in the first quarter compared to
$60 million in the same quarter last year and $66 million in the prior quarter. The decreases versus both comparative quarters are primarily attributable to the Inverness expansion and Huguley restart projects, both of which were successfully brought online in the fourth quarter of 2017.

Included in the first quarter capital investments is $23 million for the Grande Prairie, Alberta debottlenecking project. The Grande Prairie mill is one of the largest single-line OSB facilities in the world, but the mill is currently bottlenecked in the areas before the forming line and press. The Company is undertaking a project to redeploy the wood handling, heat energy and drying equipment from the unfinished and unused second production line to debottleneck the existing first line. Upon completion in the second half of 2018, the mill’s production capacity is expected to increase by 100 MMsf (3/8-inch basis) to support growing demand from key customers, and further savings are expected to be realized through reduced wood and natural gas usage. The project is budgeted at $55 million.

lso included in the first quarter capital investments is $4 million for the Inverness mill modernization and expansion project. The original two press lines will be demolished during the second quarter of 2018 and a new finishing end will be installed during the third and fourth quarters of 2018. Total capital spending for the project is currently $138 million to-date. The project cost is expected to total
$145 million, 7% above the $135 million budget due to significant fluctuations in the relative values of the Pound Sterling, Euro and US dollar currencies over the two-year life of the project.

Norbord’s 2018 capital expenditure budget is $175 million for projects focused on reducing manufacturing costs and increasing productivity across the mills (including the Grande Prairie debottlenecking project), as well as investments to support the Company’s strategy to increase the production of specialty products for industrial and export markets.

Operating working capital was $218 million at quarter-end compared to $171 million at the end of the same quarter last year and $127 million at year-end 2017. The year-over-year increase is primarily due to higher North American OSB prices and shipment volumes as well as inventories associated with the new Inverness line and restarted Huguley mill. The quarter-over-quarter increase is primarily due to higher North American OSB prices, the annual seasonal log inventory build in the northern mills in North America and the payment of year-end profit share accruals. Working capital continues to be managed at minimal levels across the Company.

At quarter-end, Norbord had unutilized liquidity of $503 million, consisting of $153 million in cash and $350 million in unused credit lines. The Company’s tangible net worth was $1,305 million and net debt to total capitalization on a book basis was 24%, with both ratios well within bank covenants.

Developments

In March, the Company announced that a shortage of wood will cause it to temporarily suspend production at its OSB mill in 100 Mile House, British Columbia. Norbord currently expects the suspension to commence on or about May 14, 2018 and to continue for approximately one month.

The significant wildfires that the province of British Columbia experienced in the summer of 2017 seriously damaged logging areas surrounding the 100 Mile House mill. Further, the severe weather conditions this winter have limited loggers’ ability to access the forests during the months when the mill typically builds its annual log inventory. Combined, these extraordinary circumstances have impacted Norbord’s ability to secure a sufficient wood supply to operate the mill on a continuous basis during this one-month period.

Norbord will continue to supply its customers with production from its other OSB mills and the 100 Mile House mill will continue to receive log deliveries during this period. The Company currently estimates that the curtailment will negatively impact its second quarter 2018 financial results by approximately $5 million. The 100 Mile House mill has a stated annual production capacity of 440 million square feet (3/8-inch basis), or 6% of the Company’s North American stated annual capacity.

Although Norbord believes it has a reasonable basis for making these forward-looking statements, readers are cautioned not to place undue reliance on such forward-looking information. By its nature, forward-looking information involves numerous assumptions, inherent risks and uncertainties, both general and specific, which contribute to the possibility that the predictions, forecasts and other forward-looking statements will not occur. Factors that could cause actual results to differ materially from those contemplated or implied by forward-looking statements include: assumptions in connection with the economic and financial conditions in the US, Europe, Canada and globally; risks inherent to product concentration and cyclicality; effects of competition and product pricing pressures; risks inherent to customer dependence; effects of variations in the price and availability of manufacturing inputs, including continued access to fibre resources at competitive prices; availability of rail services and port facilities; various events that could disrupt operations, including natural or catastrophic events and ongoing relations with employees; impact of changes to, or non-compliance with, environmental regulations; impact of any product liability claims in excess of insurance coverage; risks inherent to a capital intensive industry; impact of future outcomes of tax exposures; potential future changes in tax laws; effects of currency exposures and exchange rate fluctuations; future operating costs, availability of financing, impact of future cross-border trade rulings or agreements; ability to implement new or upgraded information technology infrastructure; impact of information technology service disruptions or failures; and other risks and factors described from time to time in filings with Canadian securities regulatory authorities.

Except as required by applicable law, Norbord does not undertake to update any forward-looking statements, whether written or oral, that may be made from time to time by, or on behalf of, the Company, whether as a result of new information, future events or otherwise, or to publicly update or revise the above list of factors affecting this information.

Norbord defines Adjusted EBITDA as earnings determined in accordance with International Financial Reporting Standards (IFRS) before finance costs, income taxes, depreciation, amortization and non-recurring or other items; Adjusted earnings as earnings determined in accordance with IFRS before non-recurring or other items and using a normalized income tax rate; and Adjusted earnings per share is Adjusted earnings divided by the weighted average number of common shares outstanding (on a basic or diluted basis, as specified). Adjusted EBITDA, Adjusted earnings, and Adjusted earnings per share are non-IFRS financial measures, do not have any standardized meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other companies. See “Non-IFRS Financial Measures” in Norbord’s 2017 Management’s Discussion and Analysis dated February 1, 2018 and Q1 2018 Management’s Discussion and Analysis dated May 2, 2018 for a quantitative reconciliation of Adjusted EBITDA and Adjusted earnings to earnings (the most directly comparable IFRS measure).

Norbord is a leading global manufacturer of wood-based panels with assets of US$1.8 billion and annual sales of approximately US$1.8 billion. Norbord has 17 operations in the United States, Europe and Canada.
